Hi Dan,

I was searching for some information about mixed distributions and came across to your blog. I went through your posts and those help me. But, my problem is a slightly I think so!Suppose that we have 5 random binary (0 and 1) X variables which are independently distributed. the probability of each variable is p1,p2,…,p5. Let Y denotes as the sum of those X variables then the problem is to find the expected value and variance of Y.

I was wondering if you help me.

Thanks,

Amin.
